Assignment Instruction:
The problem is to be done according to the AISC LRFD Method or the AISC ASD Method. All given loads are service loads unless otherwise indicated. Assume adequate lateral support of the compression flange such that lateral stability does not control. Assume all standard sections are equally readily available in the indicated grade of steel (even though actually they are not). A figure showing span and loading is required, and a final check of strength is required.
Problem:
For the case assigned, select the lightest W section to carry a uniformly distributed dead load wD in addition to the beam weight, and a uniformly live load wL as indicated. The member is simply supported and deflection is not of concern.
The assigned case is Case 3. Additionally assuming the live load deflection may not exceed L/360 (not an AISC Specification requirement).

- Give me right solution according to the question. As a compression member, a W18x119 is utilized. The length of the piece is 12 feet. What is the compressive strength of A992 steel if it is used? Use the manual's table as a guide. Calculate both the LRFD design strength and the ASD allowed strength.End Condition: Both ends are fixed against rotation and translation.arrow_forwardIf you can't solve this question just skip it but don't say this is an assignment question.arrow_forward
